Both Panasonic FZ200 and Olympus 1 have 12.0 MP resolution sensors but Panasonic FZ200's sensor is 1/2.3-inch (6.17 x 4.55 mm ) and Olympus 1's sensor is 1/1.7-inch (7.44 x 5.58 mm ).
Since Olympus 1's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Panasonic FZ200.
Below you can see the FZ200 and 1 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic FZ200 and Olympus 1 Cameras
As seen above, Olympus 1 has a 1.5x Larger sensor area than Panasonic FZ200. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Panasonic FZ200 and Olympus 1 sensors have been tested by DxO and the results show that 1 has a better overall score of 51, 14 points higher compared to FZ200's score of 37.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Panasonic FZ200
or the
Olympus 1 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/1.7-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
